NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting, and repair of the product. Be prepared
to collect the fluid with suitable containers before
opening any compartment or disassembling any com-
ponent containing fluids.
Dispose of all fluids according to local regulations and
mandates.
Fuel Tank
Fuel quality is critical to the performance and to the
service life of the engine. Water in the fuel can cause
excessive wear to the fuel system.
Water can be introduced into the fuel tank when the
fuel tank is being filled.
Condensation occurs during the heating and cooling
of fuel. The condensation occurs as the fuel passes
through the fuel system and the fuel returns to the
fuel tank. This causes water to accumulate in fuel
tanks. Draining the fuel tank regularly and obtaining
fuel from reliable sources can help to eliminate water
in the fuel.
Drain the Water and th e Sediment
Fuel tanks should contain some provision for draining
water and draining sediment from the bottom of the
fuel tanks.
